In what has been described as a softener for unpopular Marine Park borders, and a political move to delay hardships until after the next state elections has been dismissed by Premier Jay Weatherill.

"This is a very important reform which I think has been through one of the best public consultation processes I have seen in government," Mr Weatherill told 891 Breakfast.

Shadow environment and conservation minister Vicki Chapman said the Premier was aware there was 'enormous public anger' about the new parks.

"Consultation has just been a con," Ms Chapman said.

"We had the Select Committee interim report delivered this week and the very next morning the government go out and basically say 'blow that, we are not interested in reading that, we're doing what we want to do'."

Mr Weatherill dismissed Ms Chapman's claims, saying an overwhelming majority of the Local Advisory Group recommendations were accepted.

"85 per cent of what's under there, in the marine environment, is only found in our southern waters.

"There is incredible diversity there; greater than the Great Barrier Reef."

Mr Weatherill said an enormous amount of work had been done to ensure that all of the popular South Australian fishing spots had been protected and were still accessible to recreational fishers.
